Description
117795/3 6,7 DIHYDRO-3-(2-NITROPHENYL) 1,2-BENZISOXAZOLE-4(5H)-ONES AND PHARMACEUTICALLY ACCEPTABLE ADDITION SALTS THEREOF ϋ"·]ΊΝ-(5Η) -"?πκυϊ?"ΐυΊΤ:α-2,1 (^Ί]9Τ"Ιϋ",]-2)-3-'ΠΤ,Π",7 7,6 TJ^NIEI TTTODTQ ττ'ριπριιπ TJ^DITD ΌΤΓΡΓΠ The present invention relates to dihydrobenzisoxazolines of formula 6. o wherein X is hydrogen, loweralkyl, halogen, loweralkoxy, hydroxy, or trifluoromethyl. The above compounds are valuable intermediates in organic synthesis , and especially for the preparation of compound s of copending patent application No, 100921 , from which the present application has been divided out.
As used throughout the specification and appended claims, the term "alkyl" refers to a straight or branched chain hydrocarbon radical containing no unsaturation and having I to 8 carbon atoms. Examples of alkyl groups are methyl, ethyl, I -propyl, 2-propyl, I -butyl, I -pentyl, 3-hexyl, 4-heptyl, 2-octyl and the like. The term "alkoxy" refers to a monovalent substituent which consists of alkyl goup linked through an ether oxygen having its free valence bond from the ether oxygen. Examples of alkoxy: groups are methoxy, ethoxy, propoxy, I -butoxy, I -pentoxy, 3-hexoxy, 4-heptoxy, 2-octoxy and the like. The term "alkanol" refers to a compound formed by a combination of an alkyl group and hydroxy radical. Examples of alkanols are methanol, ethanol, 1- and 2-propanol, 2,2-dimethylethanol, hexanol, octanol and the like. The term "alkanoic acid" refers to a compound formed by combination of a carboxyl group with a hydrogen atom or alkyl group. Examples of alkanoic acids are formic acid, acetic acid, propanoic'acid, 2,2-dimethylacetic acid, hexanoic acid, octanoic acid and the like. The term "halogen" refers to a member of the family fluorine, chlorine, bromine, or iodine. The term "alkanoyl" refers to the radical tonned by removal of the hydroxy function from an alkanoic acid. Examples of alkanoyl groups are formyl, acetyl, propionyl, 2,2-dimethylacetyl, hexanoyl, octanoyl, anhydride, octanoic acid anhydride and the like. The term "lower" as appl to any of the aforementioned groups refers to a group having a carbon skeleton containing up to and including 6 carbon atoms.
The present invention comprehends all optical isomers and recemic forms thereof of the compounds disclosed and claimed herein and the formulas of the compounds shown herein are intended to encompass all possible optical isomers of the compounds so depicted.
The novel dihydrobenzisoxazoiines of the present invention are prepared by the process delineated in Reaction Scheme A.
To prepare a dihydrobenzisoxazole β of the present invention, a 2-nitrobenzhydroxamic chloride 4 is condensed with a cyclohexan-1 ,3-dione enamine 5 to provide a 6, 7 - dihydro-3-(2-nitrophenyl)benzisoxazol-4(5H)-one 6, EXAMPLE 1 6,7-Dihydro-3-(2-nitrophenyl)-1,2-benzisoxazol-4(5H)-one To a solution of 1 ,3-cyclohexadione morpholine enamine (20.8 g), tetrahydrofuran, (150 ml), and triethylamine (2 ml) at reflux was added a solution of 2-nitrobenzhydroxamic chloride (17.7 g) in tetrahydrofuran (100 ml) dropwise over 2 hours. The reaction mixture was heated under feflux for 1 hour and then evaporated. The residue was partitioned between 3n hydrochloric acid, 10% sodium carbonate solution, saturated sodium chloride solution, dried over anhydrous magnesium sulfate, filtered, and the filtrate was evaporated. The residue was chromatographed on silica gel with ethyl acetate as the eluent. The appropriate fractions were collected and evaporated. The residue was recrystallized from dichloromethane/hexanes to yield 15.0 g (66%) of product, mp 125-127°C.
